Application mea november frame 9 and the Wheels, so that they are freeTo all whom it 'may concern:

Be it known that l', Janes iivnnniv, a citizen of the United States,residing at Montgomery, in the county ot lontgomery and State ofAlabama, have invented eertain new and useful l'inprovements in SafetyAppliances for Railways; and ldo hereby declare the following to be afnll,'elear, and exact description of the invention, such as willvenable others skilled in the art to which it appertains to make. and usethe saine.

This invention relates vto safety railway appliances, and has for itsobject to improve the appliances heretofore invented by me, andyespecially those such as are disclosed in my prior Patent #897,864,issued September 8, 1908.

W ith these ends in view, the invention consists in the details ofconstruction and combinations of parts more fully hereinafter disclosedand particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspeciieation, in which like miniera-ls relier to like parts in all theviews :--l `igure 1 is a fraq'mentary View in side elevation of aportion ol a passenger truck with my im proveniente applied thereto;Fig. 2 is an end elevational AView ot the parts shown in Fig. 1; Fig. 3is a view similar to Fig. l, but showing my improvements applied to afreight trneli instead ot a passenger truck; Fig. is a view partly insection of a moi'flitied torni ot box and safety roller support; is aside elevational View showing` a further'nodilied torni ot safety deviceapplied to a truck; Fig. (3 is an end elevational view' of a portion otthe truck shown in Fig. 5; Fig. 7 is a sectional View 4or certain of'the parts shown in Fig.

6 and illustrating` the safety device applied g to the safety wheel; andFig. 8 a perspective Vview of the' safety journal plate detached fromthe truck.

1 indicates the track, 2 the wheels of the truck, 3 the axle on whichsaid Wheels are mounted, 4- the 'journal box, 5 the pedestals adapted tomove up and down relatively to Athe boxes fi, G the equalizer beams, 7the longitudinal beams, and S' the transverse beams of my truck.

9 represents a safety frame bolted as Aat 10 to the equalizer beams lG,and passingl unA der the projecting bottom 11 of the boxes Ai, as shownin Figs. 1 and 2. The pedestals 5, .as best shown inllig. 2, passbetween the Specification of Letters Patent.

to move up and down regardless of said frame. The said. frame 9 in thisinvention is extended entirely across the face of the Wheel and beyondthe same, as shown in Figs. 1 and 3, and at their ends opposite to thatof the ends 10 is secured a transverse safety tie rod or bar 13, whichextends parallel to the axle 3 and is secured on the other side of thetruck to a similar bar or frame 9, as will be readily understood. Therod or bar '13 is located below and substantially parallel with thebrake beam 14C, and carries immediately beneath the brake shoes 15 thecurved safety pieces 16 adapted to catch the said brake shoes shouldthey become aecidentally detached, and thereby prevent the same fromfalling between the wheels and track and causing a dei-ailment. Said bar13 also Carries Carved safety pieces 17, as

best shown in Fig; 2, which are located imthe safety trame t) and itscoacting parts in jroper position should any ot' said parts break.'tlhese chains 19 are omitted tor the sake of elearness in Fig.

ln the lorm ot truelt shown in Fig. 3, the pedestals are omitted, andthe satety frame t) passes directly through the castinzgI 21tsupportingAthe safety rollers Q5, as will be readily uinlerstood, ln both Figs. 1and 3, the brake beam is likewise omitted for the salte et clear-ness.

ln the modilird form ol journal box 30, shown in Fie'. it, the said boxand safety roller bearings 31 are made integral, and the safety traineSl passes `.nnlerneath a projecti 3i? east upon said box, and-preciselysimilar to the ledge .ll shown in Fig. 2. rthis ,artienlar forni ot' boxand roller bearings is exeelalingly stront', in that there are no partsto .ne bolted together, and it is likewise very ehea p and simple toconstruct, for that. it is readily made in a single casting.

ln addition to the above, the tansverse beam S is provided withsafety'sleeve supi ports whieh are scoured to said beanr S lin ' journalthe inner safety 'wheels 3l are mounted, as

in niy patent above.

Referring more particularly to the inoditied term oit inventionillustrated in Figs. 5, 3, 7 and 8, l atta eh directly to Athe truckiinmediately above the journal boit, a safety l ,te 5G which may besecured' by the bolts l passing through the truck on each side et thejournal bor., as shown, or by any other suitable means. i preferably addin 'this instance also a trengthening arch bar o2, which passes abovethe dange 53 of the safety journal plate, and also passes .flown to thesatetytrarne 9 disclosed above,

to which it may be secured in any suitableL manner. The safety journalplate 50 is bent as shown 5ft to pass over the tread oit the wheel El,and it rnay be. provided., if desired, with a' grooved Vlportion 55,which will lit the flange 56 oiifsaid wheel 2. In itsnornial osition tiebent ortion 54 rests a short distance above the tread of the wheel 2,but when a journal breaks upon the outside, naturally the whole truckwill fall, and said parts 54 and 55 will firmly rest upon the tread ofthe Wheel and its. flange 56, thereby supporting the structure, andpreventing the saine from falling to the road bed until the air brakesare applied, and thereby averting what might otherwise be a seriouswreck by a broken journal. As best shown in Figst and 7, l may likewiseattach to the tie rod 18 as at 58, a safety strap or bar 57 which'passes over and partially encireles the safety wheelf37, and is securedto the lower center bolster 59 o't the truck. This safety strap 57 islikewise normally located a short distance above the tread 60 of thesafety wheel 37, and should an equalizer beam, or an arch bar such as'61, ora journal break, naturally the truck would drop, but in thatevent the said strap 57 would catch upon the tread GO of the safetywheel 37 and the Whole structure would be held up until the air brakesare applied, and thereby avoid what would otherwise be a serious wreck.

The operation of my improved safety appliance is as toll'ows:-Should anaxle such as l break between the'wheels, the safety sleeve 36 will stillaccommodate the ends of the broken axle, and the tie rod ltogether withthe safety frames 9 will hold the boxes t lirinly against the outerfacesof the Wheels 2 'from spreadinff and consequently hold the ends of thebro ren axle within said sleeve 35. It results, therefore, that in caseof an axle breaking between the Wheels, that the car will. not leave thetrack, and will still. go" on a considerable distance with perfectsafety until the train is stopped. lShould the axle break outside of theWheels, then .'the weight of the truck or loadr will cause thetransverse beams 8 to descendlthereby.

naanoo causin 1' the safety supports to rest upon the sate-ty sleeveand'tliis sleeve'in turn will transfer the strain back.V to the wheels2, which are tirinly on the track. ln the case of a loose wheel, such as2, the inner ends of the boxes will be held iirinly by the tie rod i3against the outer faces of said wheels, and thereby prevent the saidwheels from ,spreading outwardly. 'lthe safety wheels 37 in the saineway will prevent said wheels from coming` together inwardly. ln eithercase, the standard gage is still maintained and consequently myilnprmfements insure against dei-ailments from loose wheels.

Since the 'tie rods 13` extend troni one side of the truck to the other,and since the saiety fraines) are so firmly secured to the enactingparts'of the truck, my said tie rods serve to solidify or strengthen theentire truck as a whole. They further serve to prevent the pedestals 5from swinging outward in case of deraihnent, in that the said pedestalspass just inside of said. rods S). ln addition to the above, should thewheel leave the track, it naturally produces twisting action upon thejaws of the pedestals 5, and since the safety frames 9 tit outside ofsaid pedestals, this twisting motion due to a, deruilinent or to othercauses is eileetually resisted. Further, the catches 1'6 and 17 carriedby the tie rodi?) eieetually prevent the brake shoes 15 or the b'akebeams la :troni falling in front of the wheels, and thereby causing' aderailrnent. Again, in. the building of new trucks, lf ani enabled bythe construction shown in Fig. 4, to do away with the neces sity ofbolting; the roller :training to 'the journal box, and ain enabled tosupply' a. cheaper and stronger construction of combined 'journal boxesand safety roller bearings than has been hereto torepossible. lnaddition to the above, the safety devices best shown in Figs. 5 to 8enable the entire trainework of the truck to be hold up in the case ot abreakage of a. Dart. ',lhisholding` up of the frame-work of the truck,is also aecomf panied by gripping ol the wheel 2 by the plate 50, whichelicctually prevents said tually guards against this common forni otWree s.

Of course, the wheels are equipped alike on both sides of the truck.

lt will be understood that in all cases et the breakage of a portion ofthe truck, l

izo

senese ai provide suitable means for automatically applying the brakesand stopping the train,

one example ot' such means being disclosed in my patent above.

lt is evident that those skilled in theaarl. may vary the details ofconstruction and the arrangement of parts Without departing troni thespirit of my invention, and thereil'oi'e, ll do not wish to be limitedto such features as disclosed7 except as maybe required by the claims. f
